Filter/Water Issues

Hi Iya.

IMHO Bauer is NOT more comprehensive with the data, they just didn't disclose the fact that there TUV approved separators were not up to the job in hand.
That and because of the number of explosions they had with there original TUV approved separators they changed the material improved the tensile strength.
Originally their separators (M76 thread on a 95mm OD and 270 length) were rated by TUV for 350 barg but also only designed under TUV for ridiculously
minimal 2.5 to 1 safety margin.

It frankly was an accident waiting to happen IMHO the german TUV lot acted clueless as to the material, wall thickness tensile strength and internal thread
architectures, but in typical germanic approach expected everyone else to comply.

In the UK we didn't, and years later as they started to explode under load. (The material was HE30TF or 6082 the Germans designate this as ALMG SI1 F31
it will be stamped on the shell, but another critical flaw was that the working pressure to burst was only 2.5 to 1) Therefore only a 12,000 pig burst design

The redesign issued is now with a 4:1 safety boundary, so now a 20,000 psig burst design.

Most filters and separators now are designed under the ASME 4:1 safety code if the external and or internal dimensions need to be the same as the older
weaker material then the tensile strength of the alloy needs increasing. The old HE30 TF or 6082 or ALMH SI1 F31 has a tensile strength of around 270 Mpa

By comparison most new designed filters are in 7075 T6 alloy with a tensile of over 500 Mpa, also to factor in thinner wall thickness but with greater
strength in a non corroding atmosphere. Zuführung durch die Technik des Esels eines Esels,

Hi There Ian,
Yes I did once read on this alloy change, you wrote this info too some years ago. Many thanks.
My stuff are all the new alloys, still I dont like applying too much pressure cycles.

IYA

Hi,
IYaDiver,
Helped with some tips on My Oceanus bauer compressor.
This was used by paintball idiot over 250 hours on filter and oil had ten times normal amount in it.
Still cleaning out the thing air is clean of oil however slight smell.I really don't want to pull all the lines and clean then out.

A word to the wise when your buying a used compressor from paintball or scuba guys.
Thanks for the Help on this site,
Seahunt Jerry
